Why choose our 0.25mm tinplate cans? The unique combination of a thin yet robust steel sheet and an epoxy coating provides superior protection against mechanical damage and chemical reactions. Compared to thicker tinplate (0.30mm+), our cans save material costs without compromising safety. The double seam closure is tested for leak resistance under vacuum and pressure, ensuring your food products remain fresh during long-distance shipping and storage. Additionally, the epoxy lining is free from BPA (upon request) and complies with global food contact regulations.
Our manufacturing process undergoes strict quality control at every stage: from coil slitting to welding, coating application, and seam inspection. We use automated double seam machinery that guarantees consistent seam dimensions (length, thickness, overlap). Each batch is sampled for burst pressure test, leak test, and coating adhesion test. This ensures that every can leaving our factory meets the specifications required for your specific food product.

Frequently Asked Questions
-
Q: Are these cans suitable for acidic foods like tomatoes or fruit juices?
A: Yes. The epoxy coating is specifically formulated to resist organic acids, sulfur compounds, and salts. It prevents metallic flavor transfer and corrosion, making it suitable for high-acid and low-acid foods alike. -
Q: What is the shelf life of food packed in these cans?
A: With proper double seam sealing, the shelf life typically ranges from 2 to 5 years, depending on the food type, storage conditions, and initial processing. The airtight seal and epoxy barrier effectively prevent spoilage. -
Q: Can I get custom sizes other than the standard 100-500ml range?
A: Yes, we can produce cans with different diameters and heights, as long as the thickness remains 0.25mm. Please provide your desired dimensions or volume, and we will confirm feasibility. -
Q: Do you offer printing or labeling services?
A: Absolutely. We support lithography printing (up to 6 colors), screen printing, and plain label wrapping. We can also apply your brand artwork or barcode. Minimum order quantities apply for custom printing. -
Q: What is the minimum order quantity (MOQ)?
A: For standard sizes, the MOQ is 10,000 pieces per specification. For custom sizes or printing, the MOQ may be higher (e.g., 50,000 pieces). Please contact our sales team for exact numbers. -
Q: How do you ensure the double seam quality?
A: We use automatic double seam machines with real-time monitoring. Every production shift performs seam tear-down tests, and final inspection includes leakage testing under vacuum. Our QC team follows ISO sample plans. -
Q: Are these cans BPA-free?
A: Our standard epoxy coating does not contain BPA. However, if you require a BPA-free specification, we can supply cans with a specially formulated BPA-NI (non-intent) epoxy lining. Please confirm your requirement. -
Q: What is the lead time for a typical order?
A: For standard cans without printing, lead time is 15–20 working days after order confirmation. For custom sizes or printed cans, lead time is 25–30 working days. Rush orders may be possible with prior arrangement.
